i'MPROVEMENT IN MECHANISNI FOR OPERATING CHURNS.

Speciiication forming part of Letters Patent No. 12, l 29, dated March29, 1864.

To all whom it may concern.-

Beit known that l, GEORGE TRUE, of Funchal, in the Island of Madeira,have invented a new and Improved Self-Acting Barrelv Ohurn and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming a part of this speciication, in which- Figure 1represents a front elevation of my invention. Fig. 2 is a transversevertical section of the same, the line m m, Fig. 1, indicating the planeof section.

Similar letters in both figures refer to corresponding parts.

The object of this invention is to arrange a barrelchurn in such amanner that the churning will be accomplished by the action of thegravity of the barrel and its contents, and of a iiy-wheel and a seriesof gear-wheels whereby the velocity of the descending barrel isregulated.

The invention consists in a barrel hung upon pivots and adjustable in ahoop which forms bearings for the pivots of the barrel, and which isprovided with gudgeons that have their bearings in carriages moving upand down on suitable uprights arranged in combination with two toothedracks and suit able gearing in such a manner that the barrel can bereadily brought in an upright position to receive the cream and thenadjusted in the rotary hoop to any desired inclination, and wound up tothe top of the toothed racks, whence it descends by its own gravity,slowly rotating all the while, and that by this motion the operation ofchurnin gis accomplished.

To enable those skilled in the art to make and use my invention, I willproceed to describe it.

A represents a frame, made of wood or any other suitable material, andprovided withl two uprights, B, which form the guides for the slidingcarriages C C'. These carriages straddle the toothed racks D D', whichare rigidly attached to the inner surfaces of the uprights B, and theyare provided with lugs or ears a, which form the bearings for ahorizontal shaft, E. This shaft carries two pinions, b b', one at eachend, and these pinions gear into the toothed racks D D'. The pinion b'at one end of the shaft E also gears in a cog-wheel, c, which is securedto an arbor, c', and meshes -the gear-wheels on the opposite" side.

- into a pinion, dii, on an arbor, d', which also carries a cog wheel,d, and this cog-wheel meshes into a pinion, 0*, on an arbor, c', whichalso carries the oog-wheel e, and tin ally the cogwheel c meshes into apinion, f", that is rmly secured to one of the gud geons of the rotatinghoop E. The arbors c' d' e' have their bearings on one end in thesliding carriage C', and on the other end in a bracket, e2, which isrigidly attached to the carriage G'. The pinion e* on the arbor e' is soarranged that it can be shifted in a longitudinal direction and thrownin gear with the toothed rack D', or I with the cog-wheel d, said arborbeing provided with a key, so that it is compelled to rotate with thepinion, Whether the same be in gear with the rack or with the cog-wheel.The hoop E is provided with two gudgeons, f', which have their bearingsin suitable journal-boxes, f, on the top ofthe sliding carriages C C',and one of these gudgeons carries the pinion ft, as above stated, andthe other the ily-wheel F, which is intended to regulate the motion andto counterbalance the weight of hoop forms the bearings for the pivotsg, which support the barrel G. These pivots are rigidly attached to thecentral part of the body of the barrel, and two segmental lian ges, h,are secured, one to each of the heads of the barrel. The edges of theseanges form portions of a circle described from either one ofthe pivots gas the center and they are guided between ears t', secured to theopposite ends of the hoop E. Two pins, j, passing through holes in theears t' and anges h, retain the barrel in the desired position andprevent it from rotating on the pivots g, and a series of holes, k, insaid dan ges allow of adjusting the barrel to any desired inclination.`By withdrawing the pins j the barrel can be turned in an uprightposition, and by removing one of the heads when in this positionconvenient access can be had to the interior of the barrel forchargingor discharging. The operation is as follows: In order to chargethe barrel and wind it up, the pinion e* p is introduced by removing thehead, and after The t-he head has been refastened the barrel is adjustedto the desired inclination by means of the pins j, and the churn isfinali y wound up to the top of the racks D D. The pinion c* is nowshifted on its arbor c and thrown in gear with the wheel d, as indicatedin red in Fig. l, and the churn is started. The weight of the barrelwith contents and of all the cog-wheels and fly-wheel must besoregulated that it will overcome the friction of the gear-wheels and thechurn will run down by its own weight. The cream in the barrel, onaccount of the oblique position of the latter, will act as a sort ofregulator, so as to prevent the churn from attaining a higher velocitythan desirable, and the time which it takes the churn to run down willdepend upon the height of the racks and upon the proportion ofthegearing.

In practice the gearing will be so arranged that the butter hassuiicient time to form' and the churning will be completed when thechurn has run down, and all the dairyman has to do is to fill the barrelwith the desired quantify oi.'

cream, set it, wind up the churn, and start it, and the churn willcomplete the operation of churning by its own gravity.

What I claim as new, and desire to secure by Letters Patent, is

l. The barrel G, hung upon pivots g, in a rotary hoop, E, in combinationwith the toothed racks D D', sliding carriages C C', and suitablegear-whcels and piuions, all constructed and operating in the manner andfor the purv poscsubstantially as described.

2.' The sliding pinion e*,in combination with the gear-wheels c d c,rack D', sliding carriage C', and barrel G, constructed and operatingsubstantially as and for the purpose set forth. I 3. The application ofthe segmental flanges IL to the heads of the barrel G when the latter ishung upon pivots g in the rotary hoop E, substantially as and for thepurpose specified. GEO. TRUE.
